If the driving surface is loose or slippery, following distances should be increased by how much?

When driving on loose or slippery surfaces, such as gravel, wet roads, or ice, it is essential to increase your following distance significantly to ensure safety. The recommended increase of two times the normal following distance provides a greater buffer zone, allowing for more time to react in case the vehicle ahead suddenly brakes or loses traction.

On slippery surfaces, vehicles have a longer stopping distance due to reduced traction. Doubling the following distance helps prevent collisions and gives the driver additional time to maneuver safely, accommodating the slower acceleration and braking capabilities inherent in these conditions.

This strategy aligns with defensive driving principles, which emphasize anticipating potential hazards and allowing sufficient space to respond safely. It’s crucial to adjust your driving behavior based on road conditions and ensure that you're maintaining a safe following distance.
